[Linux-gpib-general] Problems with NI GPIB-USB-HS

[Riccardo <r.d...@ti...>]

Hello,

I'm having problems using the linux-gpib driver with the GPIB-USB-HS.
The ibtest program doesn't work:

  $ ibtest
  Do you wish to open a (d)evice or an interface (b)oard?
          (you probably want to open a device): b
  enter name of interface board (or device) you wish to open: ni_usb
  trying to open board named 'ni_usb'
  failed to open board

  $ ibtest
  Do you wish to open a (d)evice or an interface (b)oard?
          (you probably want to open a device): d
  enter primary gpib address for device you wish to open [0-30]: 8
  trying to open pad = 8 on /dev/gpib0 ...
  libgpib: IBOPENDEV ioctl failed
  libgpib: error in is_cic()!
  ibdev error

  ibsta = 0x8000  < ERR >
  iberr= 0
  EDVR 0: OS error

  ibcnt = 19
  Aborted

It the first time I use gpib, so maybe it is due to a
misconfiguration.

I have compiled the version 3.2.06 from CVS in the kernel 2.6.15.
When I plug in the the interface the device driver are created:

  crw-rw----  1 root gpib 160, 0 2006-03-22 15:21 /dev/gpib0

and dmesg gives me:

  usb 5-4: new high speed USB device using ehci_hcd and address 11
  Linux-GPIB 3.2.06 Driver -- Kernel Release 2.6.15.6
  /usr/src/linux-gpib/driver/ni_usb/ni_usb_gpib.c: ni_usb_gpib driver
  loading
  ni_usb_gpib: probe succeeded for path: usb-0000:00:1d.7-4
  usbcore: registered new driver ni_usb_gpib
  gpib: registered ni_usb_b interface

My /etc/gpib.conf is:

interface {
	minor = 0
	board_type = "ni_usb"
	name = "blue"
	pad = 0
	sad = 0
	timeout = T3s
	eos = 0x0a
	set-reos = yes
	set-bin = no
	set-xeos = no
	set-eot = yes
	master = yes
}

device {
	minor = 0
	name = "voltmeter"
	pad = 8
	sad = 0
}


Any suggestion?

Thanks in advance,
Riccardo
